It's not a water hazard. It's a wetland.
And ketchup is a vegetable.

Thursday (March 30), Interior Secretary Gale Norton called a press conference to claim our long nightmare of wetlands loss had finally come to an end due to unprecedented gains since 1997.

Researchers long ago established that natural wetlands such as marshes, swamps and prairie potholes are far more productive than even the best-designed artificial wetlands. And sharp-edged water bodies like water hazards, farm ponds, and even reservoirs offer very little for wildlife. Putting man-made ponds in the same class as natural wetlands is like ranking pen-raised quail with wild coveys.
